Bentworth Energy operates an in-country cementing laboratory purpose-built to support oil, gas, and geothermal projects across Africa. Based in Nairobi, Kenya, our laboratory is staffed by qualified technicians and operates in full compliance with API, ISO, and QHSE requirements.
In-country capability
The Bentworth cementing laboratory was established to provide regional projects with a reliable, locally based testing resource. Operating from Nairobi, we are well-positioned to support project timelines across East Africa, offering slurry design and testing grounded in local formation data and offset well experience rather than assumptions drawn from other basins. All laboratory equipment meets the calibration and testing requirements prescribed by the API RP 10B series of recommended practices, or manufacturer specifications, and carries the applicable QHSE certifications. Full testing and calibration records are maintained in-house, with access to third-party calibration services where required.
Standards We Work To
Bentworth Energy’s laboratory operations are governed by our internal Cementing Laboratory Standard, which establishes the minimum requirements for all laboratory activities and promotes consistent, high-quality execution across every project we support. All testing follows the API RP 10B series of recommended practices, the recognised industry standard for well cement testing. The specific standards our laboratory works to include API SPEC 10A (Specifications for Cements and Materials for Well Cementing), API RP 10B-2 (Recommended Practice for Testing Well Cements), API RP 10B-3 (Testing of Deep-water Well Cement Formulations), API RP 10B-4 (Preparation and Testing of Foamed Cement Slurries), API RP 10B-5 (Determination of Shrinkage and Expansion of Well Cement Formulations), API RP 10B-6 (Determining the Static Gel Strength of Cement Formulations), API RP 65, and API STD 65-2.
Our ISO certifications
Bentworth Energy holds three ISO certifications: ISO 9001:2015 for Quality Management, ISO 14001:2015 for Environmental Management, and ISO 45001:2018 for Occupational Health and Safety Management. These are not merely compliance credentials; they reflect how we operate on every project, embedding internationally recognised standards into our day-to-day laboratory practice.
Our team
The laboratory is managed and operated by qualified cementing technicians with proven experience across regional oil, gas, and geothermal operations. Our team oversees the full scope of laboratory activity, from slurry design and compatibility testing through to job-specific programme development and reporting, maintaining the technical standards and documentation discipline that well integrity requires.
With our engineering and laboratory functions based in-country, we are able to respond promptly to evolving project requirements, adapt testing programmes as well conditions develop, and provide operators with the technical support they need without the delays associated with international laboratory services.
Equipment
The laboratory is equipped to conduct comprehensive cement testing across a wide range of well conditions, including the elevated pressures and temperatures encountered in geothermal and deep gas environments. Our equipment inventory includes two High-Pressure, High-Temperature (HPHT) filter presses, an HPHT Consistometer, two Static Gel Strength and Ultrasonic Cement Analysers, Constant Speed Mixers, an Atmospheric Consistometer, a Viscometer and Rheometer, a Pycnometer, a Pressurised Mud Balance, and Salinity and Alkalinity Testers.
This capability allows us to carry out complete tests in-country, covering thickening time, compressive strength development, rheological properties, fluid loss, free water, and gel strength analysis—all without the need to send samples to external facilities.
Third-Party Testing Services
Beyond supporting Bentworth’s own cementing operations, our laboratory is open to providing testing services to other companies operating in the region. Whether for single-well testing or ongoing laboratory support across a broader campaign, Bentworth’s Nairobi-based facility offers operators across East Africa access to a credible, certified, and responsive local laboratory, without the cost and logistical burden of mobilising services from abroad. We welcome enquiries from companies seeking reliable cementing laboratory support in the region via our website.
Academic and research engagement
Bentworth Energy recognises the importance of developing technical expertise within the region. We welcome enquiries from students seeking supervised practical experience in a working cementing laboratory environment, as well as from researchers engaged in studies related to cementing, well integrity, or associated disciplines. We are open to discussing collaboration arrangements that make meaningful use of our laboratory capabilities and operational experience. Interested parties are encouraged to contact us through our website.
